CURTAlN-STRETCHER PIN.

SPEGIFIGATION forming part of Letters Patent No. 776,034, dated November29, 1904.

Application filed April 6, 1904.

To all lull/(mt it may concern.-

Be it known that LVILLIAM A. SnonMAxnn, a citizen of the United States,residing at Golumbus, in the county of Franklin and State of Ohio, haveinvented a certain new and useful Improvement in Curtain-Stretcher Pins,of which the following is a specification.

My invention relates to a new and useful improvement incurtain-stretching pins.

The object of the invention is to provide a pin having a single centralcarpet-engaging prong and a frame-like portion extending on either sideof the prong which bears on the carpet when the pin is inserted therein,securely clamping the same and obviating all tendency toward a rockingmovement, which has heretofore caused considerable annoyance in devicesof this character.

Another feature lies in forming the pin of a single piece of wire and soshaping the same that the curtain-engaging hook is supported above theinterior of the frame, which distributes the strain equally throughoutthe frame.

Finally the object of the invention is to pro vide a device of thecharacter described that will be strong, durable, and efficient, simpleand comparatively inexpensive to make, and efiicacious in its purposes.

With the above and other objects in view the invention consists of thenovel details of construction and operation, a preferable em-' bodimentof which is described in the specification-and illustrated in thedrawings,where- 1n- Figure l is a top plan view of the pin. Fig. 2 is afront elevation. Fig. 3 is a rear elevation; and Fig. 4: is a sideelevation illustrating the pin in engagement with the carpet and showinga portion of alace curtain caught over the hook, the carpet beingillustrated in section.

In carrying out my invention I employ a single piece of wire bent andtwisted upon itself to form a pin. The pin comprises an extended prong1, having its outer end 2 pointed and given a slight upward curve tofacilitate the ready introduction of the same into the carpet and toassist in maintaining the same in engagement therewith. The prong SerialNo. 201,837. No model.

1 at its rear end merges into a loop 3, from which the wire forming thepin is extended and bent to form the angular clamping-frame 4, which isbridged at its forward central por tion 5 over the prong l toaccommodate the thickness of the carpet. The free end of the frame ispassed upward through the loop 3 and terminates in a forwardly-extendinghorizontal arm 6, from which projects the upwardly-extending hook 7,having the bent end 8, which when the curtain is engaged over the hook 7prevents the upward displacement of the same. It is to be observed thatthe arm 6 extends centrally over a portion of the prong 1 within theframe and, as illustrated in the drawings, joins with the hook 7 at apoint substantially central of the frame. However, the exact distanceover the interior of the frame at which the arm 6 extends may be variedasmay be necessary. It is obvious that when the pin has been inserted inthe carpet until the same is clamped between the prong 1 and the frameL, which will rest evenly on the same, it is impossible for the pin torock, the frame forming a broad and substantial base which. assumes anylateral strain directed upon the hook 7. In operation I employ severalof these pins, which are engaged with the carpet at intervals and sopositioned that the four sides of the curtain to be stretched may bereadily caught over the hook 7.

I do not wish to limit myself to the exact details of construction andoperation herein set forth, as I may make various changes in the samewithout departing from the spirit of my invention.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a curtain-stretching pin, a central prong, a base-frame disposedover the prong, and acurtain-engaging hook disposed over the frame.

2. In a ci.1rtainstretching pin formed from a single piece of wire, anextended prong, a frame extending from the rear end of the prong overthe same, and a hook supported from the rear end of the prong.

3. In a curta-in-stretching pin formed from Too a single piece of wire,a central carpet-engaging prong formed With a loop at its rear i end, anangular clamping-frame extending} forward from the loop and having itsrear end passed through the said loop, an arm eX- 3 tending forward fromthe rear end of the frame over the same, and a hook projecting upwardlyand bent from the arm. l

4. In a curtain-stretching pin,

tended curved prong, a rectangular clampingframe connected to the prongat its rear end a a central exand bridged over the same, an armsupported from the rear end of the prong and extending paralleltherewith to a point substantially central of the frame, a hookextending upwardly from the arm bent at its upper end to preventdisplacement of the curtain.
